WINDOVI FASTE1\TEB.

Application filed April 22, 1915.

0 oil whom it may concern: I

it known that 1, WILLIAM C. Fox, citizen of the United States. residing at Seattle, in the county of King and State of lVashington, have invented a certain new and useful Improvement in Window-Fasteners, of which the following is a specification.

My invention relates to improvements in window fasteners and the object of my improvements is to provide a window fastener for a window that is hinged o1- pivotally mounted in a windowframe, which fastener shall be adapted releasably to lock said window in its closed position or in a position at any desired angular distance from such closed position.

I attain this object by-devices illustrated in the accompanying drawings wherein Figure 1 is a perspective view of a window and window-frame showing my invention as applied thereto; Fig. 2 is an enlarged fragmentary view of the same in front eleration showing the window locked in its closed position; Fig. 8 is an enlarged fragmentary view of the same in horizontal section on broken line m, a of Fig. 2; Fig. 4 is a like view of the same on broken line y, y of Fig. 2; Figs. 5 and 6 are perspective views each of a detail of my invention.

Referring to the drawings, throughout which like reference numerals indicate like parts, a window 7 is pivotally mounted within a window-frame 8, in a manner well known, to adapt it to be turned on its pivots for a distance of 90 degrees between a closed position and a wide open position.

A fixed rod 9, preferably of brass, is mounted in brackets 10 and 11 which are secured by screws to the inner side of the window-frame 8 whereby said rod 9 is disposed to extend vertically adjacent to and parallel with the opening through said window-frame 8, as more clearly shown in Fig. 2, and the bracket 10 is provided with an integral. stud 12 which projects horizontally beyond the adjacent edge of the window-frame 8 to adapt it to engage with a latch 13, of a form more clearly shown by a perspective view of Fig. 6. which latch 13 is fixed on the upper end of a vertically disposed rod 1 1 that is slidably mounted in the inwardly projecting flanges of brackets 15, 16 and 17 which are secured by screws to the adjacent vertical rail of the sash of Specification of Letters Patent.

Serial No. 23,011.

the window 7, as shown in Fig. 2, so that, when the window 7 is closing, the stud 12, acting in an obvious cam-like manner, will raise the latch 13 to such point as will permit its angular hook-like point to pass over said stud 12, whereupon it, with its rod l t, may fall to latch on said stud 12 securely to hold the window 7 in its closed position shown in Figs. 2 and 3.

To insure the falling of the rod 14 in the operation of latching the window 7 in its closed position, I have provided a helical compression spring 18 disposed to surround the lower end portion of the rod 14!: to extend between the underside of the flange of the bracket 17 and a knob 19 secured to the lower end of said rod 11; the knob 19 serving as a finger-hold when it is desired to unlatch and open the window 7.

To limit the downward movement of the rod 1 1 I have provided an integral projection 20 that is disposed to adapt it to enwith the top side of the flange of the bracket 15.

Thus by swinging the window 7 to a closed position it will be latched automatically and it may be readily unlatched to open it by pressing upwardly on the knob 19 to raise the latch 13.

In order that the window 7 may be fastened when unlatched and disposed with its plane at a required angle with respect to the plane of the window frame 8 to open it to a desired degree, have provided devices comprising a sleeve 21 that is slidably and rotatably mounted on the rod 9, said sleeve 21 having a clamping screw 22, by which it may be secured at a desired vertical position on said rod 9, and havingvan integral lug 23 disposed to pr ject toward the opening through the window-frame 8.

Articulated with the lug 23 is the lower end of a rod 2 1 whose upper end is articulated with a swivel 25 which is detachably connected with the inwardly projecting flange of the bracket 15; said swivel 25 being provided with an integral cross-bar 26 on its upper end above its pivot portion 27 while the flange of the bracket 15 is provided with a pivot bearing hole that is formed to have oppositely disposed slots 28 whereby the cross-bar 26 may pass through such flange to permit the swivel 25 to move rotatively on its pivot portion 27.

The relative circumferential positions of said cross-bar 26 and said slots 28 are such that only when the window 7 is in its closed position can the swivel 25 be connected and disconnected from the bracket 15 by moving the sleeve 21 to obviously required positions on the rod 9.

As the window 7, in its operation moves from its closed position, the cross-bar 26 ceases to register with the slots 28 thus to prevent the swivel 25 from being withdrawn from its bearing in the bracket 15 and as such window 7 continues swingingly to open (the clamping screw 22 being loose) the sleeve 21 is raised higher and higher on the rod 9 and the cross-bar 26 recedes farther from the slots 28; and when the window 7 is disposed at the desired angular distance from its closed position then it may be fastened securely by turning the clamping screw 22 to clamp the sleeve 21 in a fixed position on the rod 9.

Manifestly changes may be made in the forms, dimensions and arrangement of parts of my invention without departing from the spirit thereof.-

VVhat I claim is:

1.. The combination with a window frame having a sash pivoted therein to swing on an axis parallel to one edge of the frame; of a rod fixed to the frame parallel to said edge, a sleeve slidably and rotatably mounted on the rod, a plate fixed to the sash, a stud swiveled in the plate, and a connecting rod having its ends pivoted to the sleeve and stud respectively.

2. A window fastener comprising a sleeve connected to a window frame for vertical movements, a clamping screw adapted for securing said sleeve in adjusted positions, a bracket secured to the window-sash, a link pivoted at one end to said sleeve, and a swivel pivoted to the other end of said link, said swivel and bracket being provided with cooperatin means whereby the former is separable mm the latter when the swivel is suificiently rotated.

3. A window fastener comprising connections between a window-frame and asash pivotally mounted therein, comprising a rod secured to the window frame, a sleeve slidably mounted on said rod, means for securing the sleeve in adjusted positions upon said rod, a bracket fixed to the sash, a link connected at one of its ends to said sleeve, a swivel on said link adapted to extend through an aperture provided in said bracket, and spaced means provided on said swivel to engage the bracket therebetween and arranged to permit the withdrawal of said swivel from the bracket when the swivel is moved into a predetermined rotary position. I

4. A window fastener comprising a rod secured to a window frame, a bracket secured to the window-sash, a sleeve slidably and rotatably mounted on said rod, means to secure the sleeve in adjusted positions, and a two-part jointed link pivotally connected at one end to said sleeve and having a rotary connection at its other end with said bracket, said bracket and link being adapted to be disconnected when the latter is in a certain rotary position.

5. In a device of the class described, the combination with a window frame and a sash pivotally mounted therein, a sleeve, means secured to said window frame to serve as a support and guide for said sleeve, means to secure said sleeve in adjusted position on the aforesaid means, a bracket on said sash, said bracket being provided with an aperture having a circular central bearing portion and slots extending therefrom at diametrically opposite sides, and a link hingedly connected at one end to said sleeve and provided with a head at the other end formed with a cross-bar arranged to pass through said slots when the head is introduced into the aperture of said bracket.

In witness whereof I hereunto subscribe my name this twelfth day of April, A. D.
